Q

Which type of contraction produces more force under the same conditions?

A

Eccentric- when load is lowered contractile and non-contractile tissue need to exert force to control lowering

Concentric is just contractile CT

Q

What are some likely mechanisms of DOMS?

A

Microtrauma of muscle fibers and CT
-indicated by level of creative kinase in blood

Myofibrillar damage at the Z-bands
-affects structural integrity of muscle and may cause pain

Changes in mitochondria and membrane breakdown with an increase in WBCs & prostaglandins
-Calcium accumulates in mitochondria & cause problems with ATP

Q

What are NOT likely mechanisms of DOMS?

A

Accumulation of lactic acid

Spasm-pain-spasm cycle
-no EMG activity that increases with DOMS

Q

Exercise-induced muscle soreness develops ______ after strenuous exercise when muscle fatigue is achieved. It is because of _________ & ___________.

A

During or right after, inadequate blood flow & O2, build-up of metabolites such as lactic acid

Q

What is overtraining?

A

Decline in physical performance in a healthy individual

  • fatigues more quickly
  • requires more time to recover

16
Q

What is overwork?

A

Progressive deterioration of strength in muscles already weakened by neuromuscular disease (GBS, post polio)

PREVENTION IS KEY- avoid exhaustion

17
Q

What is the closed-chain exercise guideline?

A

Begin with resistance of partial BW, then BW, then add resistance

Bilateral WB—> w/ wide BOS—> narrow BOS—>unilateral WB

18
Q

If a patient is in the acute stage of healing, what types of interventions would you do?

A 
This is the protection phase so -
RICE
Pt Ed
Cardiopulmonary training 
Gentle massage
E-stim
Gentle PROM
Muscle setting (low intensity isometric contraction)
AROM within pain-range (signs of too much mvmt are increased pain &/or inflammation
19
Q

What are some interventions for the subacute stage of healing?

A

controlled motion phase

Pt ed
Jt mob
Cardiopulm endurance
AROM in pain-free ranges; AAROM in painful range
Multi-angle sub-max isometrics
Protected closed chain
Progress to low resistance ex in pain-free range, gentle stretching, muscular endurance

20
Q

What are interventions for the chronic stage of healing?

A

return to function

Pt ed
Mob
Endurance
Stretching
PREs, open & closed chain, ecc/conc
Simple to complex mvmts
21
Q

What are some signs that activities were progressed too quickly?

A 
Jt swelling
Redness/warmth
Pain > 4hrs
Decreased strength
Early onset fatigue
Decreased fxnal usage of involved part
22
Q

What are some signs of Overuse Syndrome?

A 
Pain
Swelling
Muscle guarding
Weakness
Decreased fxn
Limited ROM
23
Q

What are factors that contribute to Overuse Syndrome?

A

Muscle weakness
Muscle length or strength imbalance
Bone malalignment
Return to activity too soon
Excessive ecc demand> tissue failure at musculotendinous region
Environmental factors (vibration temp surfaces)
